Squalene, also known as squalene, is an open-chain triterpenoid compound. Squalene is named squalene because it was originally extracted from shark liver oil. It was later found in shark egg oil and other fish, and is now found to be much more widespread than previously thought, with small amounts in fungi and human earwax. Squalene is one of the cholesterol biosynthesis intermediates and the biosynthetic precursor of all steroid substances.
